Three of the following are experimentally determined quantities. Which is the odd one out?

  • A.the order of the reaction
  • B.the rate constant value
  • C.the activation energy
  • D.the molecularity of a step

Answer: D

Molecularity follows from the mechanism assumed rather than from any measurement that can be made. The other three are all obtained by fitting a model to experimental data, and each carries an uncertainty that a proposed molecularity does not.
